Abraham's Dealing with Abimelech (Genesis 20)
In this chapter we find the second incident in which Abraham identifies Sarah as his sister. The first time was the incident with the Egyptian pharaoh in Genesis 12. Now, in Genesis 20, he does the same thing with another ruler, Abimelech. While in neither case was this a complete lie, as Sarah was his half-sister, the intent was nevertheless one of outright deception. Interestingly, the strategy backfires in both circumstances. Repeating the same mistake is not unusual for any of us. Sometimes it takes multiple times before we learn our lesson. And like everyone else, Abraham and Sarah had to grow in faith. Sometimes we think that our own "prudence" is compatible with faith when, in fact, it is not. Perhaps this is what was behind the action of Abraham and Sarah. In any event, these incidents affirm to us that God will protect His people in spite of our weaknesses or the unforeseen twists of circumstance. We all make mistakes or wrong choices. In some cases, there may be consequences. But ultimately, God will work things out for our good (Romans 8:28).
